Hi, I'm Somno Science 👋

Sleep scientist by training. AI enthusiast by obsession.

Here's what you'll find on this account:

🧠 New sleep research — broken down so you don't need a PhD to understand it
🤖 AI tools reshaping health science — reviewed honestly
💤 Sleep myths — destroyed with data
📊 Gadgets & wearables — tested by someone who actually reads the studies

I believe sleep is the most underrated health intervention on the planet. The science is wild, and most people have no idea.

Follow along if you want your timeline to be smarter about the 1/3 of your life you spend unconscious.

Let's decode sleep. 🔬

Many want to end the biannual clock changes; permanent daylight saving time (DST) is the wrong solution!
Dr. Wendy Troxel explains how DST misaligns our internal clocks from the natural light-dark cycle, with important consequences for sleep and health.

@FyreVT melatonin shifts the timing of your dream sleep stage and makes it more intense. your brain runs through more vivid stories in the same window. it isn't creating dreams, just turning up the volume on what your brain was already doing while asleep.

@janaabdelhalimm this is super common. sleeping way longer than usual throws off your body clock and you wake up mid-deep-stage. that grogginess is your body still in sleep mode. catch-up sleep doesn't pay the debt back the way it feels like it should.

One bad night of sleep doesn't move inflammation in the blood. a fresh Journal of Sleep Research meta-analysis from Sapienza pooled 35 experimental studies and 887 healthy adults and found a single night of total or partial sleep loss left IL-6, CRP, TNF-alpha and IL-1 beta unchanged. what shifted the markers was three or more nights restricted to about 4.3 hours. IL-6 rose with Hedges g 0.42. CRP rose with g 0.76. peripheral inflammation reads chronic deficit, not last night

paper: Dagum P et al. The glymphatic system clears amyloid beta and tau from brain to plasma in humans. Nature Communications. 2026. https://t.co/p0zQcDTCh6

[Somno Science @somnoscience_]

Everyone reads rising blood amyloid as the brain losing. a new Nature Communications crossover trial says it can mean the opposite. 39 adults, randomized, University of Washington. after a full night of sleep, morning plasma amyloid beta and tau ran higher than after a night awake. the brain was not accumulating, it was exporting. sleep lowered parenchymal resistance and opened glymphatic outflow, pushing the proteins out to blood. deprivation kept them trapped in tissue. the signal is clearance not the number

@babybeginner a week of this means your brain now links bed with being awake. fix: get up after 20 min of not sleeping, do something boring in dim light, go back only when sleepy. lying there makes it worse. worth seeing a sleep doc to break the cycle

[Somno Science @somnoscience_]

your body clock follows sunrise whether you want it to or not. in summer the light comes in earlier and tells your brain it is morning, even through closed eyelids. blackout curtains or a good sleep mask usually fix this completely. your brain needs darkness to stay in sleep mode. totally normal

paper: The MULTI Consortium et al. Sleep chart of biological ageing clocks in middle and late life. Nature. 2026.

[Somno Science @somnoscience_]

Sleep duration was always framed as a brain issue. a new Nature paper from the MULTI Consortium at Columbia, 500,000 UK Biobank participants aged 37 to 84, built 23 biological aging clocks across 17 organ systems using imaging, proteins and metabolmics. every system shows a U-shaped curve: under 6 hours and over 8 hours both accelerate organ aging. the lowest biological age gap sits between 6.4 and 7.8 hours but shifts by organ and by sex. short sleep ages the heart, lungs and immune system through direct pathways. long sleep reaches the same diseases through a different route, mediated by the brain and adipose tissue clocks. the binary of enough versus not enough was never the point

paper: Takahata Y et al. A Period1 inducer specifically advances circadian clock in mice. PNAS. 2026.

[Somno Science @somnoscience_]

Jet lag has no real fix. melatonin depends on exact timing, light therapy is inconsistent, and both only nudge the clock. a new PNAS paper from Kanazawa University found an oral compound called Mic-628 that does something neither can: it advances the circadian clock regardless of when you take it. Mic-628 binds the clock protein CRY1, forming a complex that directly switches on Per1, the gene that sets daily rhythm. in mice with simulated 6-hour jet lag, a single dose cut re-entrainment from 7 days to 4. both the SCN master clock and peripheral organ clocks shifted together, no timing window required. if this holds in humans, it would be the first drug that resets circadian phase through a defined molecular target

severe insomnia is genuinely debilitating, you're not overreacting to it. short-term medication is considered appropriate for severe cases like this. a referral to a sleep specialist takes the pressure off your GP and gets you someone who deals with this daily. also worth asking about CBT for insomnia if you haven't tried it, it's a structured program that works well long-term

paper: Nedergaard M. The oscillatory biology of sleep: Linkage to dementia. Science. 2026.

[Somno Science @somnoscience_]

Everyone treats the dementia risk factors as separate problems. a new Science review from Nedergaard's lab at Rochester, the group that discovered the glymphatic system, proposes they all break the same pump. during non-REM sleep, neuromodulators syncronize into slow 1-minute oscillations driving vasomotion, rhythmic vessel pulsing that flushes cerebrospinal fluid through brain tissue to clear amyloid-beta and tau. stress disrupts the rhythm. depression disrupts it. heart disease disrupts it. fragmented sleep disrupts it. same failure. the diagnosis was never the point. the signal is whether the cleaning cycle still runs

the diagnosis is actually the hard part — most people walk around with it for years before finding out. the treatment usually makes a big difference pretty fast. you will probably notice better energy, mood, and focus within the first few weeks. the adjustment to cpap takes a bit but it is worth sticking with

[Somno Science @somnoscience_]

your body clock is probably set a little later than average — it is more common than people think. late-night light exposure (especially screens) can push it even later. the most reliable fix is getting bright light first thing in the morning for 15-20 minutes — it pulls the whole clock earlier over a few days. keeping a consistent wake time matters more than what time you go to bed

[Somno Science @somnoscience_]

when your body "forgets" how to sleep it usually means your brain started linking bed with being awake instead of sleeping. quickest reset: same wake time every day, only get in bed when you're actually sleepy, and get up if you're lying awake more than 20 min. sounds backwards but it retrains the connection fast. if it's been weeks, a sleep doc can sort it out
